Waves: can be Doppler shifted, reflected, refracted, diffracted, and can undergo constructive and destructive interference.
A wave refers to a disturbance in a medium that progressively transports energy from its source to another location, without transporting matter.
In Physics, there are two main (2) types of wave and these are;
- <u>Mechanical waves:</u> an example is sound wave, which requires a medium for its propagation.
- <u>Electromagnetic waves:</u> an example is light wave, which doesn't require a medium for its propagation and can travel through a vacuum or an empty space.
Basically, some of the phenomenon associated with waves include the following:
I. Doppler shift (Doppler effect).
II. Reflection.
III. Refraction.
IV. Diffraction.
V. Constructive interference.
VI. Destructive interference.
In conclusion, all waveform can be Doppler shifted, reflected, refracted, diffracted, and can undergo constructive and destructive interference.
The cause of attraction and movement in terms of repulsion and attraction is caused electromagnetic properties of the particles. The basic rule of magnetism is like attracts unlike while like repels like. This rule is useful in the application of electricity
I'm going to ignore the <em>sd</em> as a typo and answer the rest of it.
Friction will slow down an object, and the force will create heat to warm the object up. When there's a lot of friction, sound can be heard as more energy is transferred.
He has 1 1/30 gallons, or 31/30 gallons, you can find this by setting all the fractions to a common denominator and adding them
